So far, I'm really enjoying it. I've already noticed looking at some js plugins for RPG Maker that I can read the code far easier and somewhat understand what is happening, so that's a first step in learning I think!

When you're on the page containing your bundle from the link they emailed you, there's a little icon of a present next to the box where the key appears usually. If you click that, it will allow you to convert your key to a link you can send your friend so they can redeem it instead.
